I’m glad I bought this skirt! I am just shy of 5’7” and it touches the floor. I normally wear about an 8 or 10, and I bought the large, which if I remember correctly was 10/12. I think I would have been fine with a medium, but the material is so nice that I don’t think it’s obvious that it’s a little bit on the big side. Some might not like the length, so just be aware that it is very long!
